The current owner, Dr. Howard Bellin, outfitted the home with full facilities for a plastic surgeon when he bought it for just $2 million in 1992. The six-story Upper East Side dwelling comes with exam rooms (one is pictured left) and an office, in addition to a nip-and-tuck space.

If a silicone samurai (who happens to be a homebody) steps up to the plate, renovations of what The Post describes as a $19.9 million fixer-upper might not go further than makeovers of the home's bathrooms and stairs. But as the home's real estate agent Tim Desmond admits, that's a long shot. Finding such a buyer is "like finding a needle in a haystack," he told The Post.

No room for swimming laps in this puppy. But that's not what it's about: you've got the billiards table, bowling alley and tennis court for exercise (OK, maybe it's a stretch to consider billiards a form of exercise).

For some tycoons there may come a time when collecting cars gets old. If that happens, they should buy this compound. It has a garage that is so big you can store nine buses in it. The residence spans five parcels that are purchasable individually. They contain the Main House, Lake House and Carriage House (which houses the garage).
